snorronar- SOLID TIRE.

Belt known that I, "JOH N CLARENCE Come, a CltlZQH of the United Statesof America, residing at Chicopee Falls, in the county of Hamp'den .-and'State of .Massachusettsl,

have invented new and useful Improvements n Sectional Sohd Tires,- of whch the tolr This -.i'nve'ntion relates 'the pneumatic type. '.Thesetires are in general useon yehicles designed to fry heavy loadshnd arebuilt up yers' of fabric andrubber, usually, the outer wearing surface-ortreadl'wing covered with a suitable thickness of rubber. .Tiresofthis character have to be made relatively. very w'ide and piece, .tosecure complete-vulcanization of the tire through to the center thereofand manufacturers have, therefore, resorted to the plan of building upthe tires in the shape of several: rings which are afterward fitted sideby side over the rim oft-he wheel and securely .bolted' .there to bymeans of side flangesembracing portions of the two outer rings and'thefell y. "Difficulty, however, has been experienced .in holdingtheserings firmly to the. rim of the wheel, there being a tendency, bythe clamping action ofthe flanges; to force the annular members con--stituting the tire, away from therim, particularly such of said membersas are located near' the center of the rim. To; restrain this panyingdrawing, in which,-

found impracticable as in a very short timethe bolts Will-cut intothefabric when the tire is in use.

. Inthe construction forming the subject of the present application manyof the objections above referred. to are overcome and' the 1nvent1on isfully illustrated in the accomvie'w of a 'Figure l is a cross sectionaltire embodying the improvements on a large scale, the plane of thesection being indicated by line l-l, Fig. 2-.

It is not 'de- 'sirable,however, that metal rings having.

' the functions of the rings mi-should have a bearing directly onthetire fabric which is relatively soft and resilient since thecompression and expansion of the tirebody when in use causes the ringsto rapidly wear away the body of the, tire. i a \Vhen the rings are letinto the tire body 'beddedtherein, it is impossible to do anyv IPatented J uly 22, 1913.

usual manner, and after beingproperly vulramzed, are assembled togetherside by side tire sections to'spring' away from the rim 1 .vided forinterlocking the sections one to in such man'neras to prevent the radialdistire sections a, d, c, and f so positioned in the tn'ethat the bolts9 maybe pa'ssedthere under. Those of said rings which are en-'prefer-ably made circular in 'cross section,-

- tire sections have holes nio-lded therein, trahsversely, for thereeeption ofbolts 9,

These channels alljlieain the same plane, transversely of the tire, andare concentric therewith and of larger'diameter than the diameter of therings 'm to the end that these channelsmay be lined with a rubber compound-which, in the vulcanization process, will; become hard andadherent to the Wall-- -of.the channels "0', it being of course under- 1stood that the-compound-will be so prepared as not to be brittlerwhenciired but stillbe -sufficiently "hard to constitute a, goodwearingfsurface-interposed between the rings and the tire'body andeffectually preventing, any frictional" action between the rings and thezadtire. If desired, the rings, semi-circular in cr0ss 'sect1on,'wh1chare located' 111 the outer v edges of the tire. sections 0 and f andagainst the flanges, may .belsecured to said flanges or be made integraltherewith. When the tire-sections are placed together on the rim side byside: preparatory to .being'se-- cured thereto, the total widthof thesections will slightly exceed the. Width of said" rim whereby when theflanges h are set up against these sections, by means of the nuts.

on the bolts g,'t-hey' will be compressed laterally; and, as'thematerial can not, owing to the presence of the rings m, bulge outwardradially, the part ofeach section lying below the rings will be forcedby lateral c01npression into a more intimatecontact' with the ririi b. Y
